Battery times (talk time, standby time, and more) are subject to network and phone usage.A Standby time specification ("specification") is an industry standard that is only intended to allow comparison of different mobile devices under the same circumstances. Power consumption in a standby state is strongly dependent on factors including but not limited to network, settings, location, movement, signal strength and cell traffic . Comparisons of different mobile devices using such a specification can therefore only be done in a controlled laboratory environment . When using any mobile device in real life circumstances for which the mobile device is intended, the standby time could be considerably lower and will be strongly dependent on the factors as mentioned above.
